Hi IMyself, I have found a relatively simple and quick approach to these type of problems.

First, you should quickly draw a coordinate plane and plot the points. Then draw a line between them. Now ask yourself how much do I have to Rise (Vertical Change) and then how much do I have to Run (Horizontal Change) to get to point B. Slope = Rise/Run.

In this case. To get from (1,3) to (2,6) You have to go up or "rise" 3 Units, and go across "run" 1 unit. Slope = 3/1 or 3 which is answer A. Just keep in mind if the line you draw is negative the slope will also be negative and vice versa for positive.

I think the official formula if you prefer to use it, is Slope = (Y2-Y1)/(X2-X1)

Hope this helps!

\(Slope = \frac{y2 - y1}{x2 - x1}\)

\(Slope = \frac{6-3}{2-1}\)

\(Slope = 3\)

Hence, Answer is A
